- unsafeFreeze :: MMatrix s -> ST s Matrix
- unsafeRead :: MMatrix s -> Int -> Int -> ST s Double
- unsafeWrite :: MMatrix s -> Int -> Int -> Double -> ST s ()
- unsafeModify :: MMatrix s -> Int -> Int -> (Double -> Double) -> ST s ()

Documentation
Two-dimensional mutable matrix, stored in row-major order.
bounds :: MMatrix s -> Int -> Int -> (MVector s -> Int -> r) -> r #
Given row and column numbers, calculate the offset into the flat row-major vector.
Allocate new matrix. Matrix content is not initialized hence unsafe.
unsafeFreeze :: MMatrix s -> ST s Matrix #
